Aken’ni Elao (altar tusks) are usually ivory tusks carved with scenes of ceremonies or spiritual activities. These were placed at the ancestral shrines of the Ọba and were primarily made as a historical record for documenting events. For the Edo people, the white colour of ivory represents the purity of spirituality. The Ọba owns one tusk from every elephant killed by right and reserves the right to buy the other one. Aken’ni Elao are placed in the opening in commemorative heads at the ancestral altar.
